Avaliaram-se o desempenho produtivo e a viabilidade econômica da utilização de diferentes dietas na terminação de ovinos. Foram utilizados 20 ovinos machos inteiros com sete meses de idade e peso vivo inicial de 25kg. O experimento teve duração de 60 dias, sendo que os animais tiveram sete dias de adaptação às dietas e 53 para o período de pesagens, coletas das sobras e dietas oferecidas. Utilizou-se o delineamento inteiramente ao acaso com quatro tratamentos e cinco repetições: milho + soja + feno de Tifton 85 (DR); milho + soja + caju + feno de Tifton 850 (DC); milho + soja + maracujá + feno de Tifton 85 (DM); milho desintegrado com palha e sabugo (MDPS) + feno de leucena + feno de Tifton 85 (DL). Observou-se efeito do tratamento (PThe performance and economical viability of using different diets in sheep termination were evaluated. Twenty rams aging seven-month old and averaging initial live body weight of 25kg were used. The experimental period lasted 60 days, with seven adaptation and 53 for body weight evaluation, and feed and leftover sampling. A completely randomized design with four treatments and five repetitions was used. The treatments included: corn + soybean + Tifton 85 hay (DR), corn + soybean + cashew + Tifton 85 hay (DC), corn + soybean + passion fruit + Tifton 85 hay (DM), and corn and cob meal (MDPS) + Tifton 85 hay + leucaena hay (DL). Treatment affected (P<0.05) intakes of dry matter (CMS), crude protein (CPB), and neutral detergent fiber (CFDN). Average body weight gains (g) were 171.60, 218.80, 217.20, and 187.00 for the treatments DR, DC, DM, and DL, respectively. Lower CMS, CPB, and CFDN were observed for DL. There was no effect of diets on the hot and cold carcass yields. Economical analysis indicated liquid profits of R$ -20.40, R$ 44.77, R$ 31.41, and 39.10 and return ratios of 12.4%, 31.8%, 20.6%, and 32.8% for DR, DC, DM, and DL, respectively.
